摘　　要：通过将机筒开设的螺旋沟槽由固体输送段延伸至熔融段,利用挤出机熔融段反压缩比设计的螺杆螺槽和正压缩比设计的机筒沟槽组成的强剪切系统实现物料的快速熔融,并设计了三种不同结构类型的机筒和螺杆结构,组成不同类型的挤压系统,在产量、功率能耗、停留时间、塑化效率等方面进行了对比实验研究。The helical groove of the barrel in solids conveying zone was extended to melting zone, the strong shear system was used to melt the materials quickly, which was constituted of the inverse compression screw channel and positive compression grooved barrel in the melting zone for extruder screw. Three different constructions of barrels and screws were designed to form different extrusion systems. Besides, output, energy consumption, residence time and melting efficiency were investigated eontrastively by different experiments.
